I think my subscription fee should cover it. I'd rather they do fun, meaningful content development, like class-only and even racial quests (like they do in starter zones) to obtain unique, high poly and signature gear of a race or class. Like a Sentinel's Armour or Blademaster garb.

I'm talking about 100% statless armor, sorta like the armors you get after you get Gold in all the challenge mode dungeons, just cosmetic armor with a unique look that, just like the mounts and pets offered in the cash shop, can't be obtained in any way on the game.

If you won't get ANY gear with stats (like you write), then I have absolutely so problem with it.
The look of gear is no different from a new pet/mount.
Personlly, I'd never use any money, as looks are insignificant to me..

If, however, you suddenly can buy stat-gear with RL money (RMAH, BlizzStore or otherwise) then I unsub immedately...

Would millions of people do it just so they can look nice and spiffy in their armor? They sure as hell would.

Would they be regarded as fools? Fools would be a little much, but I agree with the comment a previous poster made about "earning the gear," though. Half the fun is going through the old raid/or having the items already in your possession; pretty much confirming, "Yeah. I was there. I got through Black Temple and instead of a t-shirt, I got this nice gear."

I wouldn't mind it if the sets were only related to the mounts/pets blizz is putting out, like a celestial armor set, or an armor set based on the guardian or kirin AND it was the full set for a decent price and it wasn't found in scam/R.I.G. boxes like TOR and several other games have.

No, because we already pay a sub fee. I'm fine with it in GW2 because that's how they make their money and it can be bought with in game gold. WoW makes MORE than enough from sub fees that if they wanted to implement this it should be free.

I think if they drop the subscription cost, that'd be the best way to make up their lost revenue. However, I do not expect them to drop the subscription cost any time soon, and I sure as hell won't stay subscribed to a game that offers unique (and awesome-looking, it has to be awesome-looking) armours for money and gives us shitty tier after shitty tier of raid gear. So there's that.

To be honest when they first introduced Transmog I was expecting sets to be up on the store for sale by the first month or so. I am kinda surprised they have not already.

Personally I would not bother buying anything cosmetic from the store be it mount, pet or gear from any game. I don't get any satisfaction from buy pixels. Earning something by playing the game is more fun. For me it's not how the pixels look, but what they represent.

(Personally, I would hate it. Sure, they're optional, but for a lot of players, your own aesthetic is just as important (and sometimes MORE important) than stats. Most armor sets in the game look terrible, and if they suddenly develop a really REALLY good looking armor set, only to slap a real-money price tag on it, that would be almost insulting. This practice could be acceptable for F2P MMOs, because they have to make a profit from somewhere, but for a sub-based game, there is no excuse.)

WoW should use every excuse it can get to offer you character customisation options. It's an area it's pretty far behind on compared to more recent titles.

Frankly, It'd almost be better if they did it through the TCG than do it through the store. Keeps the armor prestigious, while making it available to people who've got some money to spend on it (like all the other loot items.)
